FBCTF is a platform designed to host Capture the Flag (CTF) competitions in both Jeopardy and "King of the Hill" formats. The platform supports competitions ranging from small groups of two participants to large events with several hundred participants. The system accommodates various participation models including physically present participants, online participants, or hybrid combinations of both. Competition organizers can use the platform to set up infrastructure, manage challenges through an administrative interface, and handle team registration processes. The platform offers flexible installation options with both Development Mode and Production Mode configurations. A Quick Setup Guide provides a streamlined installation process, while custom installations offer greater flexibility for specific requirements. FBCTF includes administrative tools for managing competitions, challenge entry systems, and participant registration functionality. The platform is designed to handle the technical infrastructure requirements for running CTF events at different scales.
